Third Spacewalk Successful

Astronauts Steven Smith and Rex Walheim spent a productive day in space on Sunday as they continued to extend the International Space Station. During their six and a half hour spacewalk, the astronauts released a clamp that held the Mobile Transporter to the newly installed S0 truss. They also hooked up a set of connectors which will allow the Canadarm 2 to move along the truss and help out future construction.
